The arm_foundationv8_defconfig currently doesn't build because it uses an external AArch64 toolchain that has been updated (Linaro toolchain) and is now based on gcc 5.x. Unfortunately, Linux 3.13 is too old to be built with gcc 5.x. As a minimal fix to make this defconfig build again, we switch to use the internal toolchain backend. At the time this defconfig was introduced, there was no support for AArch64 in the internal toolchain backend, but now that it is available, there is no reason to not use it. This makes the defconfig also more consistent with the other defconfigs. Obviously, the kernel headers used to build the toolchain are set to the fixed version 3.13, so that they match the kernel being used. While we're at it, the readme.txt file corresponding to this defconfig is updated. Runtime testing has been performed with the latest version of the ARM Foundation model.

This is the support for the ARM Foundation v8 machine emulated by the
ARM software simulator of the AArch64 architecture.
First, one has to download the AArch64 software simulator from:
https://silver.arm.com/download/download.tm?pv=2482590
Then, use the arm_foundationv8_defconfig configuration to build your
Buildroot system.
Finally, boot your system with:
${LOCATION_OF_FOUNDATIONV8_SIMULATOR}/models/Linux64_GCC-4.1/Foundation_Platform \
--image output/images/linux-system.axf \
--block-device output/images/rootfs.ext2 \
--network=nat
You can get network access from within the simulated environment
by requesting an IP address using DHCP (run the command 'udhcpc').
